FASTENING-INSERTING MACHINE.

Application filed December 13, 1920. Serial No. 430,262.

T 0 all whom it may concern:

Be it known that I, ARTHUR BATES, a subject of the King of England,residing at Leicester, Leicestershire, England, have invented certainImprovements in Fastening- Inserting Machines, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like reference characters on the drawings indieating likeparts in the several figures.

This invention relates to fastening inserting machines and moreparticularly to machines for inserting fastenings to secure togethershoe parts, as for instance, uppers to insoles as a preliminary toinseam sewing of uppers to the insoles of welt shoes.

A machine commonly used for the purpose of securing the uppers to theinsoles of welt shoes by means of fastenings is that known commerciallyas the Goodyear upper stapler which is in general of the type disclosedin United States Patent No. 1,164,784, granted December 21, 1915, onapplication of John W; 'Cosgrove. In the operation of this machinestaples ofauniform length are made'and inserted throughout the operationof securing uppers to insoles, the length of the staple being such thatan effectiveclinch of the fastening is secured in the thickest portionsof the work being operated upon, while in the thinner portions there isa slight excess of staple length in the clinched portions of the staplefastenings. No attempt has heretofore been made to provide a ma chine ofthis type with means for adjusting the length of fastenings inaccordance with the requirements of the work, though it has beenproposed to do so in other types of machines which make and drivefastenings but with very indifferent success due largely to the factthat in attempting to provide for adequate response to variations in thethickness of the work the machines became so complicated as to beprohibitive from the standpoint of expense in manufacture andmaintenance and also uncertain, unreliable and inefiicient in operation.

It is an object of this invention to provide an improved machine forinserting fastenings suited to the controlling characteristics of thework'constructed to operate with a high degree of rapidity andefliciency, to be especially sensitive to the requirements of the work,and at the same time free from the disadvantages which havecharacterized prior constructions.

It is a further object of this invention to provide an improved machinefor securing uppers to insoles in the use of which the fastenings willbe automatically varied in length in accordance with the requirements ofthe work, thus rendering the machine more readily adaptable to differentkinds of work and enlarging its'field of usefulness without. sacrificingany of the advantages which inhere from the use of the presentcommercial machine. I Important features of the invention relate to afastening inserting machine of novel organization in which the feedingmeans for tlge wire stock is operated to feed a fastening length of wireuniform in amount throughout the operations of the machine followed,under certain conditions, by'correction or adjustment in accordance withthe requirements of the work at the point. of fastening insertion.

In another aspect the invention comprises a fastening inserting machinein'which the feeding means for the wire ,stock' is operated at the endof eachcycle to feed always I the same length of wire for the fastening1 which is tovbe formed and driven in the next succeeding cycle, theconstruction and ar'- rangement being such. that correction or adofoperations of the machine and merely the corrective feed is provided forat the beginning of the cycle in which the fastening is driven, it isclear that the operator does not have to wait for a fastening'at thepoint of fastening insertion and that the machinecan be maintained at ahigh-point of speed and efficiency.

7 The invention contemplates also theiprovision of a fastening insertingmachine having both the wire feeding'means and the cutting means for thewire adjusted in accordance with. the requirements of the work at thepoint of fastening insertion, whereinthe wire feed mechanism isoperative to feed a certain predetermined length of wire which ustmentin the fastening length is made at is uniform throughout all theoperations of the machine and which provides a fastening that is at theextreme end of the range of fastenings, as to length, for which themachine is designed, and in which corrective or adjustive feed of thefastening stock may take place subsequently if demanded by therequirements of the work at the point of fastening insertion.

In a preferred form of the invention the wire feeding means is operatedat the end of each cycle of operations to provide a fastening length ofstock corresponding to the shortest fastening that the machine isdesigned to make and drive, provision beingfmade to add to the fasteninglength at t-hebeginning of each successive cycle should such anadjustment be necessary to suit the requirements of the work as measuredat the point of fastening insertion.

Important features of the invention relate to improvements in theorganization of a machine designed to insert fastenings through theuppers of shoes and into the upstanding ribs or lips of insoles tosecure these parts together preliminary to inseaming operations on weltshoes in which provision is made for variations in the length offastenings as fastening inserting opera tions proceed progressivelyalong the sides of the shoes and around the toe portions thereof wherethe requirements ofthe work may vary considerably, due to differences inthickness in closely adjacent portions and especially if toe stiffenersor boxes are used at the toe portions of the shoes.

Other features of novelty which contribute to the carry-out of objectsof the invention hereinbefore enumerated, or of other objects of theinvention which will be appar ent from a consideration of the disclosureof the invention in the specification and drawings, will be pointed outin the following detailed description and included in the claims, and itwill be understood that it is my intention to cover by claims in thisapplication all that is herein disclosed of my invention.

Fig. 7 is a detail view of the wire feed mechanism of the machine shownin Figure 6 and Fig. 8 is a detail View showing the work clamped for theinsertion of a fastening.

For the purposes of illustration the invention is shown embodied in aGoodyear upper staplii'ig machine designed to secure the uppers of shoesto the upstanding lip or rib of insoles, the machine being of the typedisclosed in said United States Letters Patent No. 1,164,784. It will beunderstood. however, that the invention is not limited to the typeofmachine shown in said Let ters Patent but that important features ofthe invention may have other and various applications and uses.Referring to Fig.- ures 1, 2 and 5 of the drawings, it will be observedthat the work is presented to a nozzle 8 through which fastenings aredriven intothe work and properly clinched by an anvil member 10. Thenthe work is presented to the nozzle and the machine started inoperation, the work is first clamped securely between the nozzle and theanvil not only to hold the work during the insertion of fastenings butto measure its thickness at the point of insertion so that faste'ningsof the proper length may be in serted as will be hereinafter fullydescribed. As shown, the anvil 10 is fixedly carried'by a head 12s'lidable in guideways provided by a stationary portion of the frame ll.Secured to or integral with the head 12 is a projecting arm 16 throughwhich passes a bolt or rod 18 having an abutment 20 between which andthe arm 16 is a spring encircling the rod 18 and providing for ayielding application of clamping pressure on the work. so that workof'varying thickness may be operated on. Pivoted at 24 is a lever 26connected to operate the anvil 10 through the rod 18 and having its uper end movably attached by adjustable link 27 to the power driven lever48. There is thus provided an anvil automatic-ally operated alternatelyto clamp and release the work and serving in connection with the nozzle8 as a'work measuring means. The timing of this part of the mechanism issuch that the work is first securely clamped during the insertion of thefastening and is then released to permit of the work being repositionedfor the insertion of a fastening in spaced relation to the precedingfastening. As shown, the wire stock for the fastenings is fed betweencorrugated feed rolls 2S and 30 I) through a guide block 32 -(Fig. 5)and over an inside former 34. In the construction shown, the end of theguide block 32 serves also as the stationary cutter. In other words, itsend 36 presents asmooth, hardened surface with which there co-operates amovable cutter 38 attached to the outside former 40. It will be clearthat after the wire has been fed in position over the inside former 34,movement of the outside former 40 in operative direct-ion will cause thecutter 38 to sever a length of wire .at the instant that the said lengthof wire is pressed against the. inside former 34 by the forked ends ofthe outside former. Continued movement of the outside former will bendthe wire into staple form about the inside former which is thenretracted out of the path of a driver, not shown, which moves downthrough the outside former to drive the staple into the work presentedagainst the end of the nozzle 8. For operating the outside former thereare provided rack bars 42 integral with or securely attached to theslide 44 at the forward end of which is the outside former 40. Meshingwith the rack bars are segmental gear members 46 at the lower end of alever 48 pivoted at 50 in the machine frame and having at its upper enda roll 52 movable along the cam path 54- in the cam member 56. Foroperating the driver in properly timed relation to the outside former,there is provided a slide 58 to which the driver (not shown) is fixedlyconnected, the said slide havingrack teeth 60 which areconstantly inmesh with a segmental gear 62 at the lower end of lever 64 pivoted at 66in themachine frame and having a roll 68 movable in a cam path 70 in thecam member 56. Pivoted at 7 2 in the frame of the machine is a lever 74which carries atone end a roll 76 for movement along a cam path 78 inthe cam member 56. Pivotally mounted at 80 to the other end of the leveris the upper end of the inside former 34 above described. Pivoted to thelever 74 intermediate of its ends by means of a universal jointfurnished in part by the plate 82 is-a rod 84, the lower end of which ispivotally secured to awheel member 86 which is freely rotatable on theshaft 88, the said rod being adjusta'bly secured to said wheel by meansof a block adjustable along the slot 90. t/arried by the wheel member 86is a set of pawls, shown at 92 in Figure 7, which are held constantlypressed against the teeth of a ratchet wheel 94 by means of a spring 96.It will be clear that as the pawls are moved in operative direction bythe wheel member 86 that the ratchet 94 will be rotated and with it theshaft 88 to which is secured the feed roll 30 referred to above. Fixedlyattached to .the shaft 88 is a gear wheel 98 which is constantly in meshwith a gear 100 (Figs. 1 and 7) on a stub shaft 102 which carries alsofixedly attached thereto the small feed roll 28 which isin posit-ion toc0-operate with. the large feed roll 30 in securing intermittent feed ofthe wire stock. The operation of the mechanism thus far describedconsists in feeding the wire at proper intervals through the operationof the rolls 2 8, 30 through the guide member 32 and across the rearedgeof theinside former 34-,

s oo'rvetwi1reerenc ter Patentt Csgo ,"o hcl f e may be had for a moredetailed description of the construction and mode of operation of thesaid mechanism. j v

It is to be observedfhowever, that there is no provision in the machinedisclosed in said Letters Patent for suiting the length of staple to thethickness of the work, asthis latter characteristic varies along variousportions successively presented for the insertion of fastenings. In theillustrative mechanism of Figures land 2, the wire is fed by the feedrolls 28 and 30 always for the longest staple that themechanism isdesigned to make and'drive, the said feeding of the wire taking place'at the end of each cycle of operations. Then as the work is measured atthe beginning of each cycleat the point where the fastening is to beinserted, the wire fed is adjusted, when necessary, at the, beginning ofthe cycle and in accordance with the thickness of the work bysubtracting from the length fed in the preceding cycle an. amountdetermined by the measurement-of the work in thejcycle in which thefastening is to be. driven. In

order to vsubtract fromthelength fed by the v feed rolls, mechanism isprovided for reversing them in their rotation and. feeding back ameasured amount determined by the thickness of the work. A specificembodiment of this mechanism willnow be described. Secured to aprojection 104 extending from the head 12-is a boltv or connecting rod106 connected by means of a pivoted link 108 to a slotted member 110carrying in the slotted portion thereof a block 112 which furnishes anabutment or shoulder 114 for engagement with a pin 116 in a bellcranklever 1-18 pivoted to the frame of the machine and held-yieldinglyin its position of rest by a spring 120 which operates-for the purposein a well known manner. Pivoted to the free end of the bell crank 118 bymeans of a universal joint is a link which is in turn pivoted by auniversal joint 131 to a wheel member 132 looselymounted on the shaft88. Carried by the wheel member 132 is a pair of pawls 134 constantlypressed by means of a spring 136 toward ratchet'wheel 138 securelyattached to the shaft 88, the pawls being held normally out of contactby a stationary shield 139, part of a larger shield 141, so that ratchetwheel 138 and shaft 88 and feed roll 30 may be turned by ratchet wheel9% in the normal regular feed from operation of lever 74. It will beobserved that the shoulder or abutment 11 1 onthe block 112 is notnormally in contact with the pin 116 in the bell crank 118, thearrangement being such that the anvil 10 may be spaced from the nozzle 8to permit of unobstructed introduction of the work between the anvil andthe nozzle andto permit of movement of the anvil toward the nozzle toclamp the thickest work that the machineis intended to operate uponwithout in any way effecting movement of the bell crank 118. Under suchconditions the wire will be fed for the longest staple by the operationof the rolls at the end of the preceding cycle. If, however, the work atthe point where the fastening is to be driven is of a thickness whichdoes not require the longest staple then the anvil 10 in its movementtoward the nozzle 8 will measure and accurately determine theclifference between the longest staple which the machine is adapted todrive and the staple which should be inserted to meet the requirements.Such measuring movement of the anvil 10 will-be transmitted to the bellcrank 118 through the abutment 114 striking the pin 116 as abovedescribed. Through the connections already described this movement ofthe bell crank 118 will cause a slight rotation of the wheel member 132whereupon the ratchet wheel 138 is moved in the same direction and withit the shaft 88. to carry the feed rolls 28 and 30 in a directionreverse from normal whereby the length of wire which was fed at the endof the preceding cycle is fed back slightly the required distance toprovide the proper staple length. It will be understood that means isprovided to release the pawls 92 from the ratchet wheel 94 at the propertime so as to permit of the reverse movement of the shaft 88 and henceof the feed rolls 28 and 30. If preferred this means may be a stationaryshield similar to that shown at 139 in Fig. 2, so arranged that at theend of their return or idle stroke the pawls 92 are lifted from thewheel 94.

Means is preferably provided for adjust ing the cutting mechanism inaccordance with variations in the lengths of wire fed by the feedingmechanism as finally determined by the work measuring or caliper ingoperations of the anvil and nozzle. Preferably, the wire cutting meansis adjusted simultaneously with the adjustment of the wire feed at thebeginning of the cycle. As shown, this adjusting means for the cuttercomprises a lever or bell crank 14:0 pivoted at 142 on the frame of themachine and having a pin 1% intermediate of its ends and located in theslot in the member 110, an abutment or shoulder 146 beingprovided on thelink member 110 for co-operation with the pin 1 14: in a manner exactlysimilar to the co-operation between the shoulder or abutment 11st andthe pin 116 in the bell crank 118 as above described. In theillustrative construction, the lever 140 is held by a spring 1&8 withits lower end in abutting contact with a stop in the form of a set screw150 set in a bracket attached to the machine frame. It will be observedupon inspection of Figures 1 and 5 that the lower ends of the lever 140is slotted as at 152 to provide a cam slot which receives a pin or stud15 1 projecting from the wire guide 32. The construction and arrangementof this part of the cutter adjusting means is such that the wire guide32 is moved toward or from the inside former 34 to provide -for a longeror shorter staple having legs or prongs of equal length and inaccordance with the, adjustment of'the wire feed which follows the workmeasuring or calipering operationabove described. It is clear that ifthe cutting means remained always in the same position irrespective ofthe length of wire fed by the wire feeding means that a decrease in thelength of Wire fed at any given time would decreasethe length of thatleg of the staple on tlie side of the inside former 34: which faces awayfrom the end of the wire guide 82, while the leg or prong of the stapleon the side of the inside former 3 1 which faces the end of the wireguide 32, would remain the same length in all of the staples. Hence, thewire cutting means is adjusted each time the length of the staple wireis altered. Moreover, since the change in the length of the staple mustaffect both of the legs or prongs, it is clear that the adjustment ofthe cutting means which decides the length of only one prong is onlyhalf ofthe adjustment of the wire feeding means. This difference in theamount of adjustment is arranged and taken care of in the cam at thelower end of the lever 1 10, the construction being such that the wireguide is controlled positively and moved the proper distance inaccordance with the requirement of the work.

As above stated pins 116 and 144: are not subjected to the influence ofthe anvil 10 during the initial movement of the anvil into work clampingposition, the pins being, in the normal inoperative position of themachine, equally displaced from the forward ends of their respectiveslots in the link 110, but atv a certain point in the advance of theanvil into work clamping po sition this lost motion is fully taken upand the shoulder at the end of each slot presses against thecorresponding pin so that as the after adjustment of the wire guideandof the feed rolls will have prongs -or le-gs of unequal length, thisis considered unimportant,

all subsequent staples for the given'thicle ness of work being perfectand the difi'erences in any case being relatively slight since thevariationsin the thickness ofthe 'work'along 'each'side of the shoe areordinarily not great in amount. v

As stated above the end 36 ofthe Wire guide 32 serves as the stationarycutter during cutting operations, a movable cutter 38 cooperatingtherewith to sever the wire; In prior constructions the cutter 38 hasusually been carried fixedly by the outside-former. In the illustrativeconstruction the cutter 38 is pivotally carried at its upper or rear endby the outside former 40 and a spring 156 is provided between the sideof the former and the movable'cutter 38 to hold the latter constantly incontact with the end 36 of the wire guide. 32 with which it co-operatesto out the Wire in every adjustable-position of the latter.

In the illustrative embodiment of the second species of the inventionthe wire is fed the same predetermined amount at the end of each cycleof operations to make the shortest staple that the mechanism is designedto make and'drive and then at the beginning of the succeeding cycle thislength of wlre 1s added to, or in other words, in,- creased in length ifa longer staple is required by the work measured at the point ofinsertion of the fastening. In the con struction shown in Fig. 3, themechanism for feeding the wire stock at the end of the cycle throughlever 74, rod 84 and ratchet wheel 94, and the mechanism for making anddriving the staple is the same as in the construction above described.Moreover, the means for. adjusting the cutting devices is the same andcontrolled in I the same way through the lever 140. There remains to bedescribed the specific mechanism for adding to the length of the staplesectionwhen a staple longer than the'minimum is requiredl' As shown, theadjusting means for. the wire feed comprises a bell crank-160 operatedin the same way'as the bell crank 118 of Figure 1 buthaving at its freeend a block 162 pivoted therein on atransverse axis and perforatedto'receive' slidablythe upper end of a rod 164, which rod is providedwith teeth 166 which face upwardly so as to'be engaged by a pawl 168projecting downwardly from a lever 1'70 pivoted to the end of the bellcrank 160 at 172 and carrying a roll 174 at its free end forco-operation with a'face cam 176 on the cam block 6, being heldconstantly incontact with the face cam-176by a spring 178. The lower endof the rod-164 'is pivotally and adjustably connected to a: pawl carrier180. which carries pawls 182 held constantly in contact with the teethonthe,

ratchet'wheel '94 by means of asp'ring 18 6,

the said ratchet being fixedly secured, as

above stated,-t-o shaft 88gup0n which the feed roll 30 is also secured.It will beclear that upon downward movement ofthelaterally-extendingarm'ofthe" bellzcrank 160, the pawl 168 will be-moveddownwardly and awayfrom the teeth on'the rod 164 thus 7 skipping some of the teeth, thenumber thus skipped depending on the measuring movement of theanvil-after the :block 112 'en. f

iubsequently cam 1'76 actuatesthelever -17 and'causes the'pawl 168 toengage 'the proper tooth on bar 164 and force the-latter downages withthe pin 116 in bell crank 1 60.

wardly so that the pawl carrier 180 will be rocked to cause rotation ofthe ratchetwheel 94'and of the shaft 88 and thus of the feed roll 30 togive the latter such additional feeding movement as will cor-respondwith the increase of staple length requiredby the -work measured at thepoint of insertion,'* if up the lost motion, the anvil initiatesmovement of the lever 160 and the link 164 downwardly to operate 7 theratchet wheel 94,

thereby causing an addition feed of the wire'double the amount by whichthe'work at the callperedpoint exceeds the minimum in -thickness. Furthermo-re the combined equal to the movement of-the anvil after theshoulder 146 on the link 110 "contacts with the pin 144 carried at the*upper end of the adjusting lever 140for the wireguide 32. a

It will be understood that according to this construction the chiefpartor all of the sectional wire for the staple-is fed at the end of thecycle and that tliencorrec; tion is made at the beginning of the suc*ceeding cycle if the work requires a longer staple than 'the minimumsize": whichthe mechanism is designed top'rovide. Thus the time requiredin feeding the wire at 0118 beginningof the cycle is considerablyshortened and thelength of time that thework isheld by the machineprevious to the-insertion of the fastening is reduced permitting aconsiderable speedingup of the "mabe driven in that cycle of operations.

in accordance with therequirements of the work'at'the point wherethefastening is to beinserted. However,'tl1e whole wire feeding operationis performed at one time instead of being divided into two steps as inthe constructions described inthe foregoing specification and in thisconstruction,

moreover, the entire feeding movement of the {feed rolls takes placeatthe beginning of the cycle so that there is a slightly longer periodof time during which the work is under the control ofthe machine beforethe insertion of the fastening. On the other hand, the mechanism whichembodies this feature of the invention is simpler in construction andpossibly less likely to require attention on thepart of the operator orof the repairman. As shown in Figure 6'the bell crank -190 is exactly;similar -in its mounting and mode of operation as the bell crankllS inFigure 1. It has pivoted to its free end by a universal joint a rod 192which-is in turn pivoted 'at-its'lower end to a shield member 194: (Fig.7) pivoted at 196 upon-the wheel member 86,-theshield having a portion198 which overlies ,the teeth on the ratchet wheel 94. Theconstructionand arrangement of the shield and of its operating parts are such thatthe teeth'on the ratchet wheel 94 are unobstructed for engagementby thepawls 92 when the longest staple is demanded bythe thickness of thework. On the other hand, as the anvil 10 movestoward the nozzle 8 from apredetermined point of separation corresponding to the greatestthickness of the work which the machine is designedto operate upon, theshield 198 will-be shifted downwardly toward the pawls so that thelatter will ride up on the shield in moving to initial position andhence mustmove off of the shield before they can engage'the teeth of theratchet 94, the timeo-ccupied in contact with the shield having theeffect of shortening'the operativestrokeof the pawls, thus lessening thelength of wirefed by the feed rolls. It will be clear-that the furtherthe shield 198 is moved downwardly the shorter will be the operativestroke of the pawls and hence the shorter will be the length of wirethat is fed-for the staple to As in the preceding constructions, themovement of the combined wire guide and cutter 32 corresponds exactly tothe: movement ofthc anvil subsequent to the time that the shoulder146on-the link -1l0 comes in contact with the pin leg-while theadjustive movement of the feed rolls during the sametime is twice thedistance of the said movement ofthe anvil. It willbe observed that thefeed rolls, according to this construction, make but onefeeding'movement to obtain the staple length suitable for the work whichhas just been measured. However, the lengthening of the time that thework'is held=by the machine prior to'the insertion of the fastening isconsidered to more than offset any nother advantageslpossessed by thisspecies of the invention over thegconstructions describedearlier-in thespecification and hence, it is preferredto use a-mechanism inwhich thewire is fed at the end of the cycle and a correction made iii-minimumtimeat the beginning o-f-thesuceeeding cycle. It will be understood,moreover,

that the features 'ofthe-invention which relate to the-means for feedingand cutting wire stock may'have other usesand applications than thatherein illustrated and that the invention is limited only bythe scope ofthe'claims hereto appended.
